Game program control method with sports equipment and human-machine interaction system

Abstract

A game program control method with sports equipment includes the following steps: capturing a user image of a user operating the sports equipment; analyzing the user image to detect a position of at least one body part of the user; obtaining an angle between a target direction corresponding to the position and a base direction; moving a target object in the game program according to the position if the angle is greater than a threshold angle; and maintaining the target object at a current position of the target object if the angle is not greater than the threshold angle. A human-computer interaction system is also provided.
